Sticky, or fixed, navigation is basically a website menu that is locked into place so that it does not disappear when the user scrolls down the page; in other words, it is accessible from anywhere on the website without having to scroll.

A recent trend in UI design is to use “sticky” navigation headers where a website’s navigation stays visible as you scroll down the page. Sticky headers can be a useful addition to a website, but they can easily become an annoying mess.
